摘要
利用SO2能与有机物中的某些基团形成可逆的弱加和物、改变电介质的介电常数、使电容发生变化的特点，制备出新型SO2气体传感器.这种传感器对SO2的灵敏度和选择性较高，具有良好的再现性和稳定性，响应时间较短，具有广泛的应用前景.
The new gas sensor for SO2 is prepared based on the mechanism that SO2 ca n form a reversible weak adduct with some organic radicals, change the dielectric constant of the dielectric, thus result in the change of it’s capacitance. This kind of sensor is distinguished by high sensitivity and selectivity to SO2, good repr oducibility and stability and a short response time.
